15+7=22
22 plus 3 times 7 is equal to 43.

No, 2 + 2 does not equal 22. 2 + 2 = 4, you prick
I notice that the ratio of the y-coefficient to the x-coefficient is the same in both equations. I think that's enough to tell me that their graphs are parallel. So they don't intersect, and viewed as a pair of simultaneous equations, they have no solution.
The solution to this equation is that h is equal to -4. You can substitute this value for h into the equation to get -4 x -9 - 6 plus 12 x -4 plus 40 equals 22, or 36 - 6 plus - 48 plus 40 equals 22.
It doesn't, it should equal 45 again. I am unsure how you got this second answer but it is wrong
572 Because 2x11=22 and 13x2=26 and 22x26=572.
22+22+28+28=100.
3 and the solution is x = -5 and y = -3 When subtracting the equations remember that a - - is equal to a + So: - 6x - - 6x = 0 Also remember that a minus times a minus that the product is always a plus.

x + y = 72 x - y = 22 Add both equations:- 2x = 94 Divide both sides by 2:- x = 47 Substitute the value of x into the equations to find the value of y:- Therefore: x = 47 and y = 25
