If 6x-7 equals 3x plus 5 what is x?
6x-7 = 3x+5 6x = 3x+12 (subtracting -7) 3x=12 (subtracting 3x) x=4 (dividing by 3)
Solve by substitution method y equals -4x - 7 y equals 3x?
y= -4x-7 y=3x 3x= -4x-7 3x+4x=7 7x=7 x=1
3x squared minus 2x when x equals 5?
You fill in for x and solve the equation3(5)^2 - 2(5)15^2 - 10; now solve
-3x2 plus 22x equals 0 how to solve?
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
How do you solve this. in parallelogram abcd diagonals ac and bd intersect at e if ac 4x plus 6 and ae equals 3x minus 1 find the value of x?
this is what you would: 4x+6=3x-1 -6 -6 ---- 4x=3x-7 -3x -3x ---- 1x=-7 ---- x=-7
Solve 3x plus 5 equals 26?
x=7
How do you solve the problem 3X plus 5Y equals 7?
To solve for two unknowns (x and y) you need two independent equations. All that you can do with the above is to express x in terms of y, as follows: 3X + 5Y = 7 => 3X = 7 - 5Y or X = (7 - 5Y)/3 or you can express y in terms of x: Y = (7 - 3X)/5
-2x plus 7 equals 3x-8?
Assuming the question is "solve for x", the answer is x=5
How do you solve g times x equals -3x plus 5?
g (x) = -3x+5 -3x= 5 x= -5/3
Solve x - 7 - 9 equals -3?
x - 7 - 9 = -3x - 16 = -3x = 13
Solve for x 3x 96-75?
x=7
How do you solve the equation 3x plus 5 equals 26?
3x+5 = 26 Subtract 5 from both sides: 3x = 21 Divide both sides by 3 to find the value of x: x = 7
How do you solve 3x (x-2)-7?
6x2=-7
3x equals 96-75 solve for x?
3x = (96-75) 3x = 21So X = 7
Solve for x 3x equals 96-75?
3x=96-75 3x=21 x=7
How to solve e to the power of 3x plus 5e to the power of x equals 7?
e3x+5 x ex =7 e3x+5+x=7 4x+5=ln(7) x=(ln(7)-5)/4
How do you solve 5 plus 4x - 7 equals 4x plus 3 - 1x?
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
