How do you solve 5x plus 2 equals 22?
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
Solve by squaring X2 equals 5x plus 2?
To solve for x: x2 = 5x + 2 x2 - 5x = 2 x2 - 5x + (5/2)2 = 2 + (5/2)2 (x - 5/2)2 = 8/4 + 25/4 x - 5/2 = ± √(33/4) x = (5 ± √33) / 2
How do you answer 2x plus 6y equals 32 and 5x-2y equals 12 using subtitution?
First, change 2x+6y=32 to x+3y=16. Then solve for x, which is x=-3y+16. Then substitute -3y+16 as x into 5x-2y=12 and solve for y. 5(-3y+16)-2y=12 -15y+80-2y=12 -17y+80=12 -17y=-68 y=4 Then substitute 4 as y in either equation to solve for x. 5x-2(4)=12 5x-8=12 5x=20 x=4 The answer is x=4 and y=4, or (4,4)
How do you solve 3x plus 5x equals 32?
add 3x and 5x together to make 8x. Then your equation will be 8x=32. Lastly, divide 8 to both sides which will make x=4.
How do you solve this equation x equals one half x subtract 4?
x = .5x - 4. Get all of the x's on one side: x - .5x = .5x - .5x -4 ---> .5x = -4 Multiply each side by 2. x = -8
How do you solve 5x-2 3x-6?
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2
What is the answer to 5x - 2 4x plus 4?
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
How do you solve 5x plus 2 equals 22?
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
Solve by squaring X2 equals 5x plus 2?
To solve for x: x2 = 5x + 2 x2 - 5x = 2 x2 - 5x + (5/2)2 = 2 + (5/2)2 (x - 5/2)2 = 8/4 + 25/4 x - 5/2 = ± √(33/4) x = (5 ± √33) / 2
How do you solve 5X plus 2 equals 3X-6?
5x+2 = 3x-6 5x-3x = -6-2 2x = -8 x = -4
How do you answer 2x plus 6y equals 32 and 5x-2y equals 12 using subtitution?
First, change 2x+6y=32 to x+3y=16. Then solve for x, which is x=-3y+16. Then substitute -3y+16 as x into 5x-2y=12 and solve for y. 5(-3y+16)-2y=12 -15y+80-2y=12 -17y+80=12 -17y=-68 y=4 Then substitute 4 as y in either equation to solve for x. 5x-2(4)=12 5x-8=12 5x=20 x=4 The answer is x=4 and y=4, or (4,4)
How do you solve 3x plus 5x equals 32?
add 3x and 5x together to make 8x. Then your equation will be 8x=32. Lastly, divide 8 to both sides which will make x=4.
How do you solve this equation x equals one half x subtract 4?
x = .5x - 4. Get all of the x's on one side: x - .5x = .5x - .5x -4 ---> .5x = -4 Multiply each side by 2. x = -8
What is 5X plus 2 equals 6X-4?
Subtract 5x from both sides. x - 4 = 2 x = 6 Check it. 5 x 6 + 2 = 32 6 x 6 - 4 = 32 It checks.

What is the answer to 5x plus 2 equals 6 plus x?
Set up the equation and then solve: 5x + 2 = 6 + x (next, get like terms together) 5x - x = 6 - 2 (next, simplify) 4x = 4 (next divide both sides by 4 to solve for x) x = 1
A point whose y-coordinate is 6 lies on the line whose equation is y equals 5x - 4 What is the x-coordinate of the point?
y = 5x - 4 Substitute 6 in for y; then solve for x: 6 = 5x -4 10 = 5x 2 = x So, the x-coordinate is 2.
