Hey there!
2(6x - 10) + 10 = 5x - 13
2(6x) + 2(-10) + 10 = 5x - 13
12x - 20 + 10 = 5x - 13
12x - 10 = 5x - 13
SUBTRACT 5x to BOTH SIDES
12x - 10 - 5x = 5x - 13 - 5x
SIMPLIFY IT!
NEW EQUATION: 7x - 10 = -13
ADD -10 to BOTH SIDES
7x - 10 + 10 = -10 + 13
CANCEL out: -10 + 10 because it gives you 0
KEEP: -10 + 13 because it help solve for the x-value
NEW EQUATION: 7x = -10 + 13
SIMPLIFY IT!
7x = -3
DIVIDE 7 to BOTH SIDES
7x/7 = -3/7
CANCEL out: 7/7 because it gives you 1
KEEP: -3/7 because it help solve for the x-value
NEW EQUATION: x = -3/7
SIMPLIFY IT!
x = -3/7
Therefore, your answer is: x = -3/7
Good luck on your assignment and enjoy your day!
