b = c
There are two numbers. If 2490 is subtracted from one number then we get the other number. The algebraic expression depicting this information is:
a + b = 2490
a - b = 2490
a + b + 2490 = 0
a – b + 2490 = 0
Which equation is written in standard form?
2x = 3y - 7
y = 2x + 3
2x + 3y = 6
4x + 9y - 6 = 0
