Answer:
Step-by-step explanation:
1) 2x + y =7 -------------(I)
x - y = 2 -----------(II)
2x + y = 7
<u> x - y = 2 </u> {Now add both the equations. 'y will be cancelled}
3x = 9
x = 9/3
x = 3
Plugin x = 3 in equation (I)
2*3 + y = 7
6+ y = 7
y = 7 - 6 = 1
Answer: a) y = 1
2) Prime factorize 12 , 15 and 18
12 = 2 * 2 * 3
15 = 3 * 5
18 = 2 * 3 * 3
HCF = 3
e) 3
Answer:
8+24
32
Step-by-step explanation:
4 times 2 is 8
6 times 4 is 24
Answer:
i have no idea but i would guess yes but dont do yes
Step-by-step explanation:
Answer:
like terms: no like terms
Coefficients:-5g and 2y
Constants: 3
Step-by-step explanation:
Like terms are terms that are the same and there`s no terms that are the same. Coefficients are numbers with variables. The numbers are -5g and 2y. The constant is number with no variables. there is one constant which is 3.
