The answer you are looking for is X = 7.
To find this answer, you first distribute 5 into (-2x + 3). In doing so, you'll get -2x - 10x + 15 = -69. Next you combine the like terms on the left side (-2x and -10x) to get -12x + 15 = -69. Now, you solve. Subtract 15 from both sides to get -12x = -84, then divide both sides by -12 to get a final answer of X = 7.
