How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
How do you solve 4x-8 equals 12?
We are given: 4x - 8 = 12Add 8 to both sides: 4x = 20Divide by four on both sides: x = 5
How do you solve 4x plus 7-3x equals 15?
4x+7-3x = 15 4x-3x = 15-7 x = 8
How do you solve 4x-6 plus 5x 13x-8?
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
How do you find the value of a variable?
you have to solve for the variable for example. 4x + 2y = 8. you would solve for y. so you subtract the 4x and you do the same to both sides and you get 2y = -4x + 8. you then divide everything by 2 to get y by itself and you end up with y = -2x + 4
How do you solve -4x plus 8 equals -4?
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
Solve 8 4x 3 19 Solve 8 4x 3 19 The sum of a number and 11 is 4 Find the number Solve 310x 3 103x 3 x 7?
8(4x+ 3)
How do you solve y equals 4x-8 and y equals 2x plus 10?
y=4x-8y=2x+10Substitute (4x-8) for y in the second equation and solve for x:4x-8=2x+102x=18x=9Now solve for y:y=4(9)-8=28(9,28)
How would you solve for y in this problem 4x plus y equals 8?
You cannot solve one linear equation in two variables. You can express y in terms of x but that is NOT solving for y.
How do you solve 4x-8 equals 12?
We are given: 4x - 8 = 12Add 8 to both sides: 4x = 20Divide by four on both sides: x = 5
Solve 8 plus x equals 4 in simplest form?
8+4x
How do you solve 16x plus 4y equals 8?
You can't solve it. But you can simplify it to get: 4x+y=2
How do you solve 4x plus 7-3x equals 15?
4x+7-3x = 15 4x-3x = 15-7 x = 8
How do you solve 4x -8 equals 5x?
4x - 8 = 5x 1) Add 8 to both sides. 4x - 8 (+ 8) = 5x (+ 8) Becomes 4x = 5x + 8 2) Subtrate 5x from both sides. 4x (- 5x) = 8 Becomes -1x = 8 Reduced to -x = 8 3) Multiply both sides by -1. Becomes x = -8
4x plus 5y equals -8?
4x + 5y = -8 is an equation with two variables. While you can solve for y = something, you won't come up with a single number. For example, 4x + 5y = -8 5y = -4x - 8 y = -4x/5 - 8/5. And you can do the same for x = something in terms of y.
How do you solve 4x-6 plus 5x 13x-8?
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
How do you find the value of a variable?
you have to solve for the variable for example. 4x + 2y = 8. you would solve for y. so you subtract the 4x and you do the same to both sides and you get 2y = -4x + 8. you then divide everything by 2 to get y by itself and you end up with y = -2x + 4
