You just need to divide both sides by 0.25:
Now the left hand side simplifies:
Step-by-step explanation:
notice the table of values, what is the value of x when y is 1, use the equation y=1-3x
Y = 15
180 = 142 + 2y + 8
180 = 150 + 2y
30 = 2y
y = 15
x = 30.5
142 = 4x + 20
122 = 4x
x = 30.5
Answer:
£180
Step-by-step explanation:
