340 / 20 = 17 -------- 3 / 4 = 0.75
4z + 3 = 6 + 2zSubtract 2z from each side of the equation:2z + 3 = 6Subtract 3 from each side:2z = 3Divide each side by 2:z = 3/2 = 1.5
5x + 7 = 4subtract 7 from both sides5x = -3divide both sides by 5x = -3/5
The 'answer' is the number that 'x' has to be in order to make the statement true.18x + 3 = 12xSubtract 3 from each side of the equation:18x = 12x - 3Subtract 12x from each side:6x = -3Divide each side by 6 :x = - 1/2
4x + 1 = 4Subtract 1 from both sides:4x = 3Divide both sides by 4x = 3/4 or .75

225/75 = 3/1225/75Divide both top and bottom by 25:9/3Divide both top and bottom by 3:3/1225/75 in lowest terms is 3.
Subtract 6x from each side: 2x + 4 = 7Subtract 4 from each side: 2x = 3Divide each side by 2: x = 1.5
9 times ? = 3Set it up in equation form:9x=3Divide both sides by 9. This will cancel out 9 on the left side of the equation, leaving x alone. On the right side, 3/9 simplifies to 1/3. Therefore, since x is alone on the left side, this leaves you your answer:x=(1/3)
(2X/3) = 1multiply through by 33[(2X/3) = 1]2X = 3divide both sides integers by 2(2/2)X = 3/2X = 3/2========check in original equation2(3/2)/3 = 1(6/2)/3 = 1 ( or just cancel 2 in numerator and denominator )3/3 = 11 = 1=====checks

3x = 2y + 3Isolate y2y = 3x - 3Divide everything by 2 to get y aloney = 3/2x - 3/2Therefore the slope is 3/2 the y intercept is (0, -3/2) and the function form is y = 3/2x - 3/2 .
