Practice with Solving Equations
Answer x = 2
Explanation 3x + 5 = 11 Subtract 5: 3x = 6 Divide by 3: x = 2
Answer y = 3.1
Explanation 2y + 1.8 = 4y - 4.4 Subtract 2y: 1.8 = 2y - 4.4 Add 4.4: 6.2 = 2y Divide by 2: 3.1 = y
Explanation 8(m + 5) = 16 Multiply 8m + 40 = 16 Subtract 40: 8m = -24 Divide by 8: m = -3
Answer x = 8
Answer c = -1
Explanation 5c - 4 - 2c + 1 = 8c + 2 Combine similar terms 3c - 3 = 8c + 2 Subtract 3c: -3 = 5c + 2 Subtract 2: -5 = 5c Divide by 5: -1 = c
