step by step:
15-g=23-2g transpose -2g to other side
15-g+2g=23-2g+2g cancel 2g on the right side, and do operation on the left side
15+g=23 transpose 15 to other side to obtain variable=constant
15-15+g=23-15 cancel 15 on the left side, and do operation on the right side
g=8 you already have the value of g
Normal way:
15-g=23-2g
2g-g=23-15
g=8
I hope this could help you...
10g + 15g + 5g = 30g
48
If a statement includes an "equals" sign ( = ) then the statement is an equation. By the way . . . it may or may not be a true statement. "10 equals 120" is not true.
A linear equation.
It is an equation of a straight line.
15g = 45 divide both sides by 15: g = 3
15g of honey is equal to 2 teaspoons of honey
This equals 1/2 cup + 1 tsp.
It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
equation
Slope for the equation y equals 7 is zero.
I use "equals" or "is".
10g + 15g + 5g = 30g
If it doesn't have an "equals" sign, then it's not an equation. It's an "expression".
An expression does not have an equals sign, An equation has an equals sign,
An example of a two step equation that equals 2 is 4 + 2x = 2. In this equation, x = -1.
An equation.
