Given equations are;<span>
2a + 3b = -1 ..................equation 1
3a + 5b = -2 ....................equation 2</span>
Now multiply equation 1 with (-3)
The equation will be;
-6a -9b = 3 …………………..equation 3
Now multiply equation 2 with (2)
The equation will be;
6a + 10b = -4 ……………..equation 4
Now add equation 3 and equation 4
-6a – 9b = 3
<span>6a + 10b = -4</span>
<span>------------------------------</span>
0a + b = -1
b = -1
Now put the value of b in equation 1
2a + 3(-1) = -1
2a -3 = -1
2a = -1+3
2a = 2
a=1
Thus the solution is (a,b) = (1,-1)

Answer:
36 degrees
Step-by-step explanation:
The whole shape is 90 degrees.
90 - 54 = 36
36 degrees
Answer:
<em>coefficient</em><em> </em><em> </em><em>because</em><em> </em><em>they</em><em> </em><em>are</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>so</em><em> </em><em>they</em><em> </em><em>can</em><em> </em><em>not</em><em> </em><em>be</em><em> </em><em>constant</em><em> </em><em>because</em><em> </em><em>it</em><em> </em><em>is</em><em> </em><em>not</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>in</em><em> </em><em>every</em><em> </em><em>week</em>
we are given

Since, we have to solve for m
so, we will try to isolate m on anyone side
so, firstly , we will get rid of 1/6
so, we can multiply both sides by 6


now, we can simplify right side

now, we can multiply them
and we get
