Reorder the terms:
9 + 3z = 0
Solving
9 + 3z = 0
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-9' to each side of the equation.
9 + -9 + 3z = 0 + -9
Combine like terms: 9 + -9 = 0
0 + 3z = 0 + -9
3z = 0 + -9
Combine like terms: 0 + -9 = -9
3z = -9
Divide each side by '3'.
z = -3
Simplifying

Answer:350,000
Step-by-step explanation:
Cost of t-shirt is £6 and hat is £2 respectively.
Step-by-step explanation:
- Step 1: Let the cost of t-shirt be x and the cost of hat be y. Form equations out of the given information.
4x + y = 26 ------- (1)
x + y = 8 ----------- (2)
Subtract (2) from (1)
⇒ 3x = 18
∴ x = 6
6 + y = 8
∴ y = 2
⇒ Cost of t-shirt is £6 and hat is £2
