B = (R+2)
3R = 2B
3R = 2(R+2)
3R = 2R + 4
3R-2R = 4
R= 4
B = R + 2, so B = 6
Answer:
0.45
Step-by-step explanation:
Y – 3x = 7
y -3x +3x = 7+3x
y = 7+3x
21 + 9x = 3y
21 + 9x = 3(7+3x)
21 + 9x = 21 + 9x
The answer is B.There are an infinite number of solutions.
Answer:
b) 25

Step-by-step explanation:
<u><em>Answer: x=8</em></u>
Step-by-step explanation:
subtraction property of equality is subtracting the same number from both sides of an equation does not change the equation.
subtract by 10 from both sides of an equation.
x+10-10=18-10
simplify
18-10=8
<u><em>x=8</em></u>
