write equations practice

Answer 1

1) Solve for x: 3x + 7 = 16
Solution:
3x + 7 = 16
3x = 16 - 7
3x = 9
x = 3

2) Find the value of y: 2y - 5 = 11
Solution:
2y - 5 = 11
2y = 11 + 5
2y = 16
y = 8

3) Solve for z: 4z/2 = 6
Solution:
4z/2 = 6
4z = 6*2
4z = 12
z = 3

4) Find the value of a: 5a + 3 = 23
Solution:
5a + 3 = 23
5a = 23 - 3
5a = 20
a = 4
