Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 <u>4x + 14y = - 24</u><u> </u> {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2
76%
76 ÷ 100 = 0.76
76/100
GCF = 4
76 ÷ 4 = 19
100 ÷ 4 = 25
19/25
76% = 0.76 = 76/100 = 19/25
76% in simplest form as a fraction is 19/25
An inequality describes a relationship between two different values. The notation a<b means that a is strictly smaller in size than b , while the notation a>b means that a is strictly greater than b .
