Make x the subject of the formula y=7x + 4
2 answers:
Y = 7x + 4
-4 from both sides
y - 4 = 7x
/ 7 on both sides
(y-4)/7 = x
Answer:
x = (y-4)/7
Answer:
x= (y - 4)/7
Step-by-step explanation:
y=7x + 4
Subtract 4 from both sides
y - 4= 7x +4 - 4
y - 4= 7x + 0
y - 4= 7x
Divide both sides by 7
(y - 4)/7= 7x/7
(y - 4)/7= x
x= (y - 4)/7
