Answer:
Step-by-step explanation:
3x +2y = 13 -----------------(i)
x + 2y = 7 ----------------(ii)
Multiply the equation (ii) by (-1) and then add.
(i) 3x + 2y = 13
(ii)*(-1) <u>-x - 2y = -7 </u> {Now, add and y will be eliminated}
2x = 6
x = 6/2
x = 3
Plug in x = 3 in equation (i)
3*3 + 2y = 13
9 + 2y = 13
2y= 13 - 9
2y = 4
y = 4/2
y = 2
As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.
For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.
So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.
