<span>solve the equation ax – c = bx + d for x:
1) Group the x terms together on the left: ax - bx - c = d
2) Group the constant terms together: ax - bx = c + d
3) factor out x: x(a - b) = c + d
4) Divide both sides of the equation by (a - b) to obtain a formula for x:
c+d
</span> x(a - b) = c + d => x = ---------
a-b
This shows that the given equation CAN be solved for x, but there is a restriction: a must NOT equal b, because if a-b = 0, we'd have division by zero (which is not defined).
Where is Victoria's solution? Please share it if you want to discuss this problem further. Thank you.
Answer:
21/3.5 =6 inches
Step-by-step explanation:
$5
The equation is true when we plug 5 in for x. So, x=5 and therefore Ron’s daily allowance is $5.
7(5+5) = 70
7(10) = 70
70 = 70 ✔️
7(10+5) = 70
7(15) = 70
105 = 70 ❌
7(15+5) = 70
7(20) = 70
140 = 70 ❌
7(20+5) = 70
7(25) = 70
175 = 70 ❌
