Subtract 7 from each side: 4x = -7
Divide each side by 4: x = -7/4 or -1¾ or - 1.75
You cannot solve one linear equation with two variables.
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)
You need to organise your question properly. 3x+2y=4 4x + 3y= 7? Is 4 4x = 44x or 4-4x or 4+4x How can there be 2 equal signs in 1 equation?
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
4x+8y=-24
You cannot solve one linear equation with two variables.
16x+9 without the rest of the equation, what this equals, I can't solve
-4x + 4y = 1
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)

4x = 16Divide each side of the equation by 4:x = 4
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
4x+8y=-24
It is: y = -4x+12
(2-r)e-rr
By using the quadratic equation formula: x = -5 and x = 3
You cant solve it unless it is an equation. To be an equation it must have an equals sign.
