Answer:
x = 3
y = 1
Step-by-step explanation:
9x - y = 26 ---------------(I)
9x + y = 28 ---------------(II)
9x - y = 26
9x = 26 + y
Substitute 9x = 26 + y in equation (II)
26 + y + y = 28 {add like terms}
26 + 2y = 28 {subtract 26 from both sides}
2y = 28 - 26
2y = 2 {divide both sides by 2}
y = 2/2
y = 1
Substitute y =1 in equation (I)
9x - 1 = 26
9x = 26 + 1
9x = 27
x = 27/9
x = 3
x = 3
y = 1
Answer:
<h2>See below</h2>
Step-by-step explanation:
Terms are variables in math.
For example: 5x + 6y = is NOT like becuase x and y equal different things
4x + 2x = is like becuase x equals the same number in both
The reason we care about like terms is because we can simplify like terms.
4x + 2x simply equals 6x.

Answer:
x > (c-b)/a
Step-by-step explanation:
ax+b>c
Subtract b from each side
ax+b-b>c-b
ax <c-b
Divide each side by a
ax/a >(c-b)/a
x > (c-b)/a
