Here's a breakdown of the solution based on your work: Step 1: Start with the given equation and substitute the value of x. The equation is 3y + 3x - 12 = -45. From your work, it appears you used x = -4. 3y + 3(-4) - 12 = -45 Step 2: Multiply and combine the constant terms on the left side. 3y - 12 - 12 = -45 3y - 24 = -45 Step 3: Add 24 to both sides of the equation to isolate the term with y. 3y - 24 + 24 = -45 + 24 3y = -21 Step 4: Divide by 3 to solve for y. y = (-21)/(3) y = -7 That's 2 down. 3 left today — send the next one.
