Answer:
Solve the 1st equation for y and then you substitute the answer of the y value to the other equation to get the x value
Number 4.
Four is a linear, it is the first composite number, as well as the first non-prime number (after 1 of course).
Answer:
a) x = 18
b) y = 35
c) t = 4.5
Step-by-step explanation:
a) x + x + x = 54
3x = 54
x = 54 ÷ 3
x = 18
b) y/5 = 7
(y/5) × 5 = 7 × 5
y = 35
c) 4t + 6 = 24
4t +6 - 6 = 24 -6
4t = 18
4t ÷ 4 = 18 ÷ 4
t = 4.5
X- 6/4=7
x-6=7×4
x-6=28
x=28-6
x=22
