7X = -5X + 24 add 5X to each side 12X = 24 divide both sides by 12 X = 2 check 7(2) =-5(2) + 24 14 = 14
7x + 2 = 5,6
X=4.2666666666667
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6
7X = -5X + 24 add 5X to each side 12X = 24 divide both sides by 12 X = 2 check 7(2) =-5(2) + 24 14 = 14
7x + 2 = 6x + 2 if and only x = 0.
7x + 2 = 5,6
11x + 2 = 26 + 7x Subtract 7x from both sides: 4x + 2 = 26 Subtract 2 from both sides: 4x = 24 Divide both sides by 4: x = 6
X=4.2666666666667
The 7x and the 5x are like terms. This means that you can add them up. Think about it, 7 x's plus 5x's equals 12x's. From there, you can divide 12 from both sides of the equation, and you will get that x = 2.
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6 ■
-3x + 2 = -7x - 22 add 7x to both sides 4x + 2 = -22 subtract 2 from both sides 4x = -24 divide by 4 x = -6
7x+2-2=16-27x = 147x/7 = 14/7x = 2
7x is still the slope, no matter what x equals.
-7x + 5 = -9 -7x = -14 7x = 14 x = 2
Subtract by 7x and divide by 2.
