Answer:
a = (r/x) -b
x = -14
Step-by-step explanation:
r=x(a+b)
Divide each side by x
r/x = a+b
Subtract b
r/x -b = a
x/2=-7
Multiply each side by 2
x/2*2 = -7*2
x = -14
Answer:
1.) a = r / x - b
2.) x = - 14
Step-by-step explanation:
1.) r = x ( a + b )
r / x = x / x ( a + b) ...( Divide each side by x )
r / x = a + b
r / x - b = a + b - b ... ( Subtracting each side by b) r / x - b = a
2.) x / 2 = -7
x / 2 × 2 = -7 × 2 .. ( multiplying each side by 2 )
x = - 14
