Just Add the equations
[ Remember, Like terms together ]
(-8x+3x) + (8y-8y) = (8-18)
-5x = -10
In short, Your Resulted Equation would be: -5x = -10
[ Can solve further, for coordinates ]
Hope this helps!
Answer:
5x + 13
Step-by-step explanation:
The 2 binomials in algebraic form are
2x + 8 and 3x + 5
Summing them
2x + 8 + 3x + 5 ← collect like terms
(2x + 3x) + (8 + 5)
= 5x + 13
Answer:
b^2+17
Step-by-step explanation:
2^3 is 8 (2*2*2=8)
b^2 stays the same bcz its a variable and we don't know its value
3^2 is 9 (3*3=9)
SO just substitute,
8+b^2+9
b^2+17
Answer:
4
Step-by-step explanation:
Answer:
21, 9
Step-by-step explanation:
If girls are x, then boys are x + 12
x + x + 12 = 30
2x + 12 = 30
2x = 18
x = 9
There are 9 girls and 21 boys
