Solve the following system ofβ2x+5)=21-7x-2y=15β
Accepted Solution
A:
Let's solve your equation step-by-step. β 2 x + 5 = 21 Step 1: Subtract 5 from both sides. β 2 x + 5 β 5 = 21 β 5 β 2 x = 16 Step 2: Divide both sides by -2. β 2 x β 2 = 16 β 2 x = β 8 Answer: X=-8
Step 1: Add 2y to both sides. β 7 x β 2 y + 2 y = 15 + 2 y β 7 x = 2 y + 15 Step 2: Divide both sides by -7. β 7 x β 7 = 2 y + 15 β 7 x = β 2 7 y + β 15 7 Answer: x = β 2 7 y + β 15 7
