4x+5 = 8
Subtract 5 from both sides:
4x = 3
Divide both sides by 4 to find the value of x:
x = 3/4 or 0.75

5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
2*2+4x-9=0 4x=9-4 4x=5 x=5/4
4x-14
4x + 5 = 13. To solve algebraic equations, you need to get the variable by itself on one side of the equation. Start by subtracting 5 from both sides >>> 4x = 8. Then divide both sides by 4 to find what 'x' equals >>> x = 2.
2x+4-x = 4x-5 2x-x-4x = -5-4 -3x = -9 x = 3
