x + 1 = -4 + 3x
or
5 = 2x
Step-by-step explanation:
Each circle = +1
each emoji = x
The emoji in this case is the 100
each shaded dot = -1
On the left hand side:
we have 1 circle = 1(+1) = 1
1 emoji = 1(x) = x
on the left hand side:
4 shaded dots = -1(4) = -4
3 emojis = 3(x) = 3x
Equating both sides of the equation:
x + 1 = -4 + 3x
collect like terms:
1 + 4 = 3x - x
5 = 2x
The equation can be:
x + 1 = -4 + 3x
or
5 = 2x
