2 step equations are equations that require 2 steps to solve it.
For example, 2x + 5 = 3x + 6
To solve for x, we must isolate it.
First subtract 2x on both sides, which is ONE step.
2x + 5 = 3x + 6
-2x -2x
5 = x + 6
The we must subtract 6 from both sides of the equation, which makes is the second step.
5 = x + 6
-6 -6
-1 = x
-1 would be the answer and we only used 2 steps to solve it.
Answer:
195 sq cm
Step-by-step explanation:
15 x 15 = 225
----------------------
3(8) + 2(3) = 30
----------------------
225 - 30 = 195 sq cm
Answer:
c
Step-by-step explanation:
because it has an equal sign
To solve this, we simply need to remember our rules about order of operations. They tell us that first, we should distribute the 2 with the rest of the parentheses.
5-2(x-3)
5-2x+6
Next, we should combine our like-terms.
5-2x+6
11-2x
Seeing as we do not know the value of the variable, the simplest form of the expression is 11-2x.
Answer:
13
Step-by-step explanation:
Create an equation: g+(G+4)(2)=35
Parentheses: g+2(G+4)=35
Distributive property: g+2g+8=35
Combine like terms: 3g+8=35
Subtractive property: 3g=27
Division property: g=9
Greg is 9. Since Ava is 4 years older you add 4 to find her age. Ava is 13. You take Ava’s age times 2 ( equals 26) then add Greg’s age (equals 35). And it should equal 35.
