( x + 1 )/ 3 = x + 2
Multiply 3 on both sides
x + 1 = 3x + 6
Subtract 6 on both sides
x - 5 = 3x
Subtract x from both sides
-5 = 2x
Divide 2 from both sides
x = -2.5

Step-by-step explanation:
Express the ratio as the number of oranges in each box, that is
box A : box B
= 18 : 36
Simplify the ratio by dividing both parts by 18, thus
ratio = 1 : 2 ← in simplest form
Answer:
a = -2
Step-by-step explanation:
7a + 10 = 2a
subtract 7a from each side
7a-7a+10 = 2a-7a
10 = -5a
divide by -5
10/-5 = -5a/-5
-2 = a
check
7 (-2) +10 = 2(-2)
-14 + 10 = -4
-4 = -4
