Answer:
x = 7
Explanation:
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Remember to follow PEMDAS.
First, distribute 4 to all terms within the parenthesis it's connected to (5x & 2), as well as 2 to all terms within the parenthesis it's connected to (9x & 3).
4(5x - 2) = 4(5x) - 4(2) = 20x - 8
2(9x + 3) = 2(9x) + 2(3) = 18x + 6
20x - 8 = 18x + 6
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 8 & subtract 18x from both sides
20x (-18x) - 8 (+8) = 18x (-18x) + 6 (+8)
20x - 18x = 6 + 8
2x = 14
Isolate the variable (x). Divide 2 from both sides.
(2x)/2 = (14)/2
x = 14/2
x = 7
7 is your answer for x.
