Which method? There is the substitution method, elimination method, and comparison method
Answer:
Step-by-step explanation:
because i don't know if the 2 is with the 4 or not I have calculated both.
x/4 + 2 = 15
<=> x/4 = 13
<=> x = 13.4 = 52
x/(4+2) = 15
<=> x/6 = 15
<=> x = 6.15 = 90
Answer:
x = 2, x = 4
Step-by-step explanation:
The equation y = 10 - 9x is a linear equation and the value of either y or x can be found by substituting the given values of either y or x.
given that y = -8, and substituting this into equation y = 10 - 9x,
we have, -8 = 10 - 9x
10 + 8 = 9x
9x = 18; dividing both sides by 9
x = 2
given that y = -26, and substituting this into equation y = 10 - 9x,
we have, -26 = 10 - 9x
10 + 26 = 9x
9x = 36; dividing both sides by 9
x = 4
